SAFETY RAZOR Application filed May 2, 1930. Serial No. 449,252.

This invention relates to safety razors and particularly to handles for manipulating detachable razor blades.

Two types of safety razors, generally speaking, have heretofore been manufactured, in one of which a handle is settable at right angles to a blade, the latter in this case being curved in the operative position, while in the other, in which the blade may be retained flat, or disposed directly between its edges, the handle and the blade are maintained in longitudinal alignment. In the latter type the blades are usually rigid, while in the former the blades, some of which are well known and provided with a number of apertures, are necessarily flexible.

In order to retain the blade at a suitable angle, relative to the surface being shaved, and at the same time to utilize a handle aligned with the blade, one object of this invention is to provide a device of the character described in which the handle is maintained, during the shaving operation, in longitudinal alignment with a flexed blade.

Another object of the invention is the provision of an organization in which the constituent elements are so coordinated structurally and functionally as to insure improved results with inexpensive material which may be manufactured at a Very low cost.

As the handle consists of a pair of sections, one of which, including a clamping instrumentality for the blade, is manipulable during assembly of the device, while the other section serves, during the shaving operation, as a hand grip portion, a further object of the invention is to utilize the latter portion, which is turnable or partly revolvable, for securing the clamping instrumentality in the engaged position.

While the guard is provided with teeth for protecting the opposed edges of the blade along the parallel portions of the latter, a still further object of the invention is the provision of protecting means for the terminals of the edges at their end portions adjoining the manipulable ends of the blade, so that the said end portions of the edges may 'nal of the support, opposite the stem, is a be prevented from accidentally cutting the surface being shaved.

Other objects and advantages of the invention will be-hereinafter specifically pointed out, or will become apparent, as the specification proceeds.

With the above indicated objects in view, the invention resides in certain novel c011- structions and combinations and arrangement of parts, clearly described in the following specification and fully illustrated in the accompanying drawings, which latter show embodiments of the invention as at present preferred.

In said drawings:

Fig. l is an elevational view of a safety razor constructed in accordance with the present invention. V

Fig. 2 is a like view, but showing the members of the clamping section of the handle in open condition, and the hand grip section in longitudinal central section.

Fig. 3 is an enlarged horizontal section taken on the line 3-3 of Fig. 1.

Fig. 4 isa horizontal section on the line H of Fig. 1.

Fig. 5 is a horizontal section on the line 6-6 of Fig. 2.-

Referring particularly to the drawings by reference characters, the numeral 10 desigso nates a blade support, which is curved in cross section and has, in longitudinal align-- ment therewith, an integral elongated stem 11. Hingedly mounted at 12 on one termiguard 13, which carries thereon opposite rows of teeth 14, to protect-the edges of a blade, and a terminal lug 15. This guard is also provided with'opposed pairs of shoulders 16, 17, and with like short posts or studs 18, pref- 9n erably three.

' As illustrated, the blade 18 is of a well known form and provided with opposed cutting edges 19, 20 and three like apertures, each designated 21. After placing the blade in position on the curved support, as shown in Fig. 2, and as represented in dot and dash lines in Fig. 4, the guard is swingable into the position shown in full lines in the last mentioned figure, in which place the studs are en- 1 gaged in the apertures 21 and the blade is said stem and disposed in said handle groove flexed. In this position the shoulders 16, 17 f0 protect the terminals of the edges 19, 20.

r retaining said handle on said stem. In testimony whereof I hereby aflix my As the hand grip portion 22, which is pro- Signature.

vided with a recess 23, is revolvable on the stem 11, and as the flat surface of the lug 15 is engageable with or adjacent the flat surface 2A of the stem, the guardis held in the engaged position when the portion 22 is revolved to turn the recess 23 out of registry with the said lug. In other words, when the inner periphery 25 of the handle rests on the semi-circularly curved periphery of the lug 15, the support is held locked.

The handle portion 22, which is provided with an elongated bore 26 to receive the stem 11, has also about midway thereof an annular groove 27. After the stem is placed in its bore, a pin 28v is inserted through the wall of the hand grip portion and fixedly retained in the stern, so that the said portion while revolvable, is held against movement longitudinally of the stem 11.

While the blade 18' rests on its support, the curved endsof the blade, between the terminals of the edges 19, 20', are freely manipulable' for placing the said blade in the required position; and while the blade is shown with three apertures 21, it will be understood that the device could be used, in connection with other blades well known in trade in which, as in the bladeknownas Gillette, for instance, slots are provided in connection with the apertures, as, for instance, in a well known commercial type of blade designed for use with different razors.

The hereinbefore described construction admits of considerable modification without departing from the invention; therefore, it is the Wish not, to be limited tothe precise arrangements shown and described, which are as aforesaid, by way of illustration merely. In other words the scope of protection contemplated is to be taken solely from the appended claim interpreted as broadly as is consistent with the prior art.

What I claim as new is:

In a safety razor, in combination, a toothed guard, a lug on said guard, a blade support having an elongated longitudinally aligned stem rigid therewith, hinge means connecting said support and said guard, a handle portion having an elongated bore to receive said stem; said handle being turnably mounted on said stem and having a recess in its upper portion, said handle having also an internal annular groove about midway thereof, said lug being movable through said recess for engagement with the wall of said handle bore above said stem, whereby on turning saidhandle said recessis movable out of alignment with said lug thereby releasably engaging said lug, terminal shoulders on said guard at the sides of said hinge means and lug to cover the term-imale of the blade edges, and a pin rigid with CHARLES AUGUSTUS MILLER.
